I think I have made a big mistake by funding my lightspeed account. Twice today I couldn't even log on. And when I could, quotes would constantly freeze on me. My CPU is top of the line and my internet connection is 24 m upload and 20 m down. I am now too scared to open a position with them and will be getting my money out ASAP. Can someone recommend a similar platform with similar rates? I won't mind paying a bit extra for reliability. I loved the execution speed of lightspeed, which is critical for my trading, but I just can't bring myself to take on this obvious increase in risk. 
I tried their demo and hated it. Their charts suck imo.
